GPU behavior changes everytime I update drivers?

Every time I've updated my GPU's drivers Ive seen changes in how it behaves. Originally I was getting high utilization for stuff that didn't require high utilization, so I reinstalled the driver, everything normalized, I was getting lower utilization, of like 50-70% in a game [FPS capped to 60]  and clock speeds of 1935 Mhz /1960 Mhz on my 1660 TI with the prefer max performance setting, which would use 100 / 120 watts and this is how it was continuously for several driver updates. I had updated my gpu again after using DDU  and now I'm getting really low utilization, around 7%, my clock speed is only 1500 MHz (for the same game) and the power being used is only 41 watts. I thought that was odd so I tried reinstalling it once more, and it's the same thing, Is there something wrong with my GPU? It's not going into that  1935 Mhz anymore on the prefer maximum performance. In DDU I  notice that it first detects my 1660 ti and then my integrated Intel HD, Should I have uninstalled that driver? I noticed this time when I tried to reinstall the driver, it auto installed as a 1660 ti  after DDU.

So by updating you mean installing the same driver set repeatedly?

For the last two and the first two I did, because the clock speed for my GPU was 400 lower but the rest has just been updating as new drivers came out. The first time i reinstalled the drivers; it fixed a utilization issue, [This is months apart] this time reinstalling the driver did not fix the very low utilization.
